帧中继配置实验

首先要把帧中继配置通：
注意点：我们把一台路由器配置成帧中继交换机（FR-SW）在全局下打入：frame-relay switching
接口下部分命令：
FR-SW：
interface Serial1/0
 no ip address
 encapsulation
frame-relay
 serial restart-delay 0
 clock rate 64000
 frame-relay
lmi-type cisco
 frame-relay intf-type dce
 frame-relay route 102 interface
Serial1/1 201
 frame-relay route 103 interface Serial1/2 301
!        

interface Serial1/1
 no ip address
 encapsulation
frame-relay
 serial restart-delay 0
 clock rate 64000
 frame-relay
lmi-type cisco
 frame-relay intf-type dce
 frame-relay route 201 interface
Serial1/0 102
 frame-relay route 203 interface Serial1/2 302
!        

interface Serial1/2
 no ip address
 encapsulation
frame-relay
 serial restart-delay 0
 clock rate 64000
 frame-relay
lmi-type cisco
 frame-relay intf-type dce
 frame-relay route 301 interface
Serial1/0 103
 frame-relay route 302 interface Serial1/1 203
路由器A：
interface Serial1/0
 ip address 10.1.1.1 255.255.255.0
 encapsulation
frame-relay
 serial restart-delay 0
 clock rate 64000
 no
fair-queue
 frame-relay map ip 10.1.1.2 102
 frame-relay map ip 10.1.1.3
103
 frame-relay interface-dlci 102
 frame-relay interface-dlci
103
 frame-relay lmi-type cisco
路由器B:
interface Serial1/1
 ip address 10.1.1.2 255.255.255.0
 encapsulation
frame-relay
 serial restart-delay 0
 clock rate 64000
 frame-relay map
ip 10.1.1.1 201
 frame-relay map ip 10.1.1.3 203
 frame-relay
interface-dlci 201
 frame-relay interface-dlci 203
 frame-relay lmi-type
cisco
路由器C：
interface Serial1/2
 ip address 10.1.1.3 255.255.255.0
 encapsulation
frame-relay
 serial restart-delay 0
 clock rate 64000
 frame-relay map
ip 10.1.1.1 301
 frame-relay map ip 10.1.1.2 302
 frame-relay
interface-dlci 301
 frame-relay interface-dlci 302
 frame-relay lmi-type
cisco
这样帧中继就可以全通了。
